Can anyone give me info as to which pitch alum prop to order for a 90hp four stroke Merc/Yamaha on a Montauk. Fresh water use not too fast. Thanks

There are a few posts to answer your question in the past, but to give you an answer now in one word, seventeen. This will give you good holeshot and keep you in the right part of the RPM range, around 5600 loaded.

I agree. I've had 2 Montauks - each with [new] 90 "2" strokes - a Rude and Johnson. Maybe a bit different than the 4 stroke you mentioned. I ran 13.25 by 17s, and wow, great holeshot, excellent speed, 45-48 WOT. I did run a stainless 13x19 once, and it was a big sluggish out of the hole, but added top end. I preferred the aluminum 13.25x17. Best, Mav

I have a 93' 90HP Johnson that tops off at 35 mph. Is something wrong? I saw the reply of 40 to 45 mph.

Yes, something is wrong. First, how are you measuring your speed? A GPS is the only real accurate way, short of a radar gun. With a clean bottom and trimmed right, you should be in your mid 40's, 40 minimum.

Bradenton FL? #5 is what a 50 will do. You should be running 42-45. What RPM's are you doing?

-Using a GPS to read speed.
-Tachometer is broken. Need new one!
I might get someone to check it out. I had the compression checked when I bought it, the mechanic said it was good.
